My previous post explained how to get custom launch params so you can respond to different calling conditions, including a call from another app, or Mobile Safari. There is also a very good chance that your app may already be running, so what then?
Handle Open URL
With multitasking, this actually becomes quite likely, because users no longer kill your app, they simply move away from it. Your app is essentially suspended, so you should probably handle the non-launch option as well.
The ApplicationDelegate class defines a method just for this use, all you have to do is override it and hook it into your webView.
Copy the following to your AppDelegate.m and add the function to your js code:
One cool thing about the handleOpenURL function is that it is easily testable. You can put a link right inside your html to make the call using your protocol and it will be processed by the OS and passed right back to your app. This may not seem useful, but I can foresee situations where it might make sense, like passing info from a ChildBrowser control back to your main app, or completely decoupling your view from your app-controller. … Any other ideas?
